Abstract (en)
[origin: WO03044586A1] A system and method for removing perspective distortion from an image of an object (112) moving along a transport device (114) having a top surface (124) is disclosed. A line scanner (110) to create a first image of an object. The first image is composed of a plurality of scan lines, each having a resolution. Each of the scan lines is then rescaled, so that the resolution of each scan line is equal to the resolution of every other scan line. Each of the scan lines is processed in two halves so that the center lines of the scan lines are co-linear after rescaling. The line scanner is optionally configured to vary its field of view as a function of the distance between the line scanner and the portion of the object being scanned.
